How do I ask question about lowercase error in casefolding?

I don't understand this error... I've already turned df into lowercase before turning it into a list dataframe:

Code:

import pandas as pd
import numpy as np
import re
import string
import nltk
 
import str

def load_data():
    dataset = pd.read_csv("jawapos_entertainment.csv")
    return dataset

news_df = load_data()
news_df.head()

df = pd.DataFrame(news_df[['judul_name','judul_kategori','judul_Headline']])
df

from Sastrawi.StopWordRemover.StopWordRemoverFactory import StopWordRemoverFactory
factory = StopWordRemoverFactory()
stopwords = factory.create_stop_word_remover()

kalimat = df [['judul_name','judul_Headline']]
kalimat = kalimat.lower()

stop = stopwords.remove(kalimat)
print(stop)

But I have an error in this line:

AttributeError                            Traceback (most recent call last)
<ipython-input-17-ce52d5ec4fb2> in <module>

      5 kalimat = df [['judul_name','judul_Headline']]
----> 6 kalimat = kalimat.lower()
      7 
      8 stop = stopwords.remove(kalimat)
~\anaconda3\lib\site-packages\pandas\core\generic.py in __getattr__(self, name)
   5463             if self._info_axis._can_hold_identifiers_and_holds_name(name):
   5464                 return self[name]
-> 5465             return object.__getattribute__(self, name)
   5466 
   5467     def __setattr__(self, name: str, value) -> None:

AttributeError: 'DataFrame' object has no attribute 'lower'

But why is the program returning a lowercase error if I've already passed the lowercase dataframe before?

You can't just lower a Dataframe object. First you have to point that you want to use vectorized string functions for Series and Index-pd.Series.str. Converting whole dataframe to lowercase format should looks like this:

for columns in kalimat.columns:
    kalimat[columns] = kalimat[columns].str.lower()
